C. Sue Carter is a biologist and behavioral neurobiologist. She is an internationally recognized expert in behavioral neuroendocrinology. In 2014 she was appointed Director of The Kinsey Institute and Rudy Professor of Biology at Indiana University. Carter was the first person to identify the physiological mechanisms responsible for social monogamy.[1][2]

Carter studies social bonding, male and female parental behavior, the social control of stress reactivity and the social control of reproduction, often using animal models such as the socially monogamous prairie vole. Carter’s research focuses on neuropeptide and steroid hormones, including oxytocin, vasopressin, corticotropin-releasing hormone, and estrogen. Her research program has discovered important new developmental functions for oxytocin and vasopressin, and implicated these hormones in the regulation of long-lasting neural and effects of early social experiences.[3] She also has a long-standing concern regarding the consequences of medical manipulations for human development and parent-child interactions, including the use of “pitocin” to induce labor and consequences of breast feeding for the mother and child. Most recently she has been examining the role of oxytocin and vasopressin in mental disorders such as autism, schizophrenia, anxiety and depression.[4] Carter is also known for research on the physiological basis of social behavior, including studies that implicated oxytocin, vasopressin and hormones of the hypothalamic-pituitary-adrenal (“stress”) axis in the traits of monogamy including pair-bond formation.[5] She pioneered the physiological study of socially monogamous mammals, including the prairie vole. In collaboration with Lowell Getz, Carter documented the occurrence of social monogamy in prairie voles. Her studies in rodents helped to lay the foundation for the studies of behavioral and developmental effects of oxytocin and vasopressin in humans which are in progress. In collaboration with Margaret Altemus she conducted some of the first studies documenting the importance of breast-feeding in the regulation of maternal physiology.

Author and LGBT activist Dan Savage claimed the announcement of Carter's appointment to Director of the Kinsey Institute was "packed with bad news for anyone interested in sex research and/or conducting sex research (particularly those conducting sex research at the Kinsey Institute)" and "Carter's pseudo-scientific/pseudo-empathetic moralizing plays right into the hands of the kind of conservative politicians who have been trying to kill the Kinsey Institute for decades." Savage criticized Carter's view that, "I think human sexuality must be viewed in the context of relationships," countering, "Not all human sexuality exists in the context of relationships. You can argue, if you're a moralist, that human sexuality should only be expressed in the context of a relationship. But that is a moral position, not a scientific one."[7]
